As much as I dislike Unity, I commend the Ubuntu team and Shuttleworth for having the guts to try to innovate and bring the desktop forward (pretty much the exact same can be said of KDE4 and GNOME3). Shuttleworth has just announced yet another significant change for Ubuntu, and it's all about replacing the menu with a search interface dubbed the HUD.

You can know the name of the command you want and still not know where the particular app you're using buried that command. As a concrete example I was using Arc Map (an app I use about twice a month) the other day and I knew there was a command called 'mosaic', but it still took me ages to actually find.

All this talk about using the keyboard as more pratical is simply bullcrap.

Have you used any apps that use this particular method to access menus? If so, which ones (and what particular problems did you have)? I have used such apps and find it far easier and more practical than just having menus. No bullcrap.
